JOHN F. SCHULTZ, OF CHICAGO, ILLINOIS.

IMPROVEMENT IN SELF-WAITING TABLES.

Speciiicationforming part of Letters Patent No. 139,267, dated May 27,1873; application iiled March 1B, 1873.

To all whom it may concern:

Beit known that I, JOHN F. SonULTz, of Chicago, in the county of Cookand State of Illinois, have invented a new and useful Improvement inRevolving Dining-Tables; and

l do declare that the following is a true and accurate descriptionthereof, reference being had to the accompanying drawing, and to theletters of reference marked thereon, and being a part of thisspecification, in which- Figure 1 is a perspective view of my table.Fig. 2 is a cross-section. Fig. 3 is a bottom plan.

Like letters refer to like parts in all the ligures. v

This invention consists in the combination of certain ratchets, paWls,rod, cord, bridgetree, spindle, with a stationary frame, centralrevolving and vertical adjustable top and outer detachable rim, as willbe fully described hereinafter.

In the drawing, A represents a central standard, from which radiate fourlegs, B, which, at the top, support a table-rim, C, secured to them. Thetop of the standard is mortised through the crossed braces D at theirintersection, and these latter have their outer ends mortised in the rimC. E is the tabletop, fitted Within the rim F, and when resting upon therim C is supported thereby. F is an annulus or rim of wood, of the samethickness as the table-top, around which it is loosely tted, and issupported on a plane therewith by folding brackets a, pivoted inmortises in the rim C, entering sockets b,` pendent from the under sideof the table-rim F, one or more of these sockets being provided with aspringcatch to prevent the disengagement of the brackets, and thus keepthe said rim stationary. If preferred, the said rim may be permanentlysecured in place. Pendent from the center oi' the table-top islaspindle, o, which is stepped in a bridge-tree, d, one end of which ishinged to one of the braces D, While the other is suspended by a cord,e, from the end of a shaft, f, journa-led ina bearing on the same brace,and through the rim C, where it is provided with a hand-wheel and aratchet,

g, with which engages a of the rim C.

By turning the hand-Wheel the cord e is wound upon the shaft, and thuselevates the table-top from its supports, when it may freely rotate withits spindle, making it very convenient for a person sitting at the tableto help himself to a dish or article at a distance from him, Which he4brings within reachby revolving the table-top. y

The bridge-tree necessarily plays in a inortise in the upper part of thestandard A, down into Which the spindle extends.

The table-rim F may be removed, and thus diminish the table in size, thelatter being made to rotate, if so desired.

This improvement is readily applied to the round tables of ordinaryconstruction.

What I claim as my invention, and desire to secure by Letters Patent, isi i The combination of the ratchets g, paw] h, rod f, cord @,bridge-treeol, and spindle o with the stationary frame, ,central revolving andvertically adjustable top, and outer detachable rim, as described.
